Problem with *.dylib

[00kian00]

Ok,I'm Chinese ,so my English it's very poor:-P


      I install some apps from ininjas in Cydia ,such as metaspolit,ettercap GTK ,windowmaker ...... When I run them in Terminal or iSSH ,it often show "cann't find usr/local/lib *.dylib ". And I can't find the similar name in "usr/local/lib" ,so I can't link it.So ,what should I do?(I have installed Libtools )

What are the dylibs names exactly.  The lib might also be in /usr/lib so you could link against that.  Or maybe there was a missing dependency.

Ettercap-ng GTK (libexpat.1.dylib)

[BooCocky]

Why did you report my post lol?  Anyway,  I just checked in my /usr/lib folder and libexpat.1.dylib is there.   It is linked against /usr/lib/libexpat.1.5.2.dylib.  So try running


ln -s /usr/lib/libexpat.1.5.2.dylib /usr/local/lib/libexpat.1.dylib

Then try running ettercap.

Maybe it was because you spelled could as coupd. :-)

There may be a different problem: the binaries have hardcoded paths for dylibs. If they aren't there, that's gotten as an error, even if the library is installed somewhere else. Check with tool -L <binary> where the libraries are supposed to be and at which version.

Sorry.....I thought it was "Reply".....

I still can't find libexpat in usr/lib or usr/local/lib (use ifile)

[00kian00]

Should I install some packages about libexpat?

[00kian00]

Ok,I fonud the awnser. Libexpat is in package ----"XML Parser Toolkit" ^_^

[BooCocky]

^OK so everything is working now?

I seem to do that alot lol.

This is why everything since the beginning of time that is third party should have just been compiled for /usr/local.  The library errors are unanimous now.   A couple of times I used the /usr directory as PATH because I was stupid and thought it was better.  Now everythings messed up

Oh god ,there have another problem:

You get this error most probably because /use/lib/libSystem.B.dylib is too old. Get a copy of that library from a recent sdk and replace your existing copy. You will also need to copy all the libraries that were once bundled in libSystem and now are in /usr/lib/system (by default the directory is empty on the device). I got this error too and fixed it this way.
